I am writing to you because I have a really serious problem, and I do not know how to tackle it.
Two weeks ago, I split up with my boyfriend and my best friend has helped me a lot. Last night, when we were chatting, things got out of control and we ended up sleeping together.
After that, we talked about it and we decided it did not mean anything. However, he has changed his mind and now he thinks I have taken advantage of him.
I miss him a lot, but anly as a friend. What can I do?
